My intentions were to mig this pan. The Tig i going to take a lot of practice to learn. I would appreciate your settings, that will give me something to work with.

I had panned on welding both sides of the seam and the short stitch method (as I call it) I learned from a body shop we rented space to back when I was in the shop. Only in body work you end up doing 1" passes. I will give 3 inch a shot though now that you recommend it.

As for the AN fittings, they will be fun. I was contemplating removing the shielding gas tube from the mig torch and making a smaller one just so its easier to get behind the fittings.
